[llvm] [llvm-exegesis] Remove redundant declarations (NFC) (PR #166044)

[Kazu Hirata via llvm-commits]

https://github.com/kazutakahirata created https://github.com/llvm/llvm-project/pull/166044

In C++17, static constexpr members are implicitly inline, so they no
longer require an out-of-line definition.

This patch removes the unnecessary "const" from the in-class
declaration as well.

Identified with readability-redundant-declaration.
